I just replaced the regulator hose on my 30 year old USD Conshelf 21 reg. It was easy - no leaks. The best advice I got here was to NOT over tighten the hose at the LP port and to NOT take the LP fitting off the regulator.

I replaced the hose because it began to leak - a crack near the LP port fitting. That was the original hose - 29 years old. I think I got my money's worth out of that one. Although I thoroughly rinse the reg - twist it submerged in fresh water to try to get all the salt out of the swivel fitting - there was still considerable oxidation inside the fitting. I am sure you have seen some REALLY corroded ones. I cleaned it as best I could on the 2nd and that was good enough - the new hose o ring sealed fine. It may be a good idea to take the hose off every year or so and clean that fitting - but then that could also damage the o ring? Changing that o ring would be a challenge without the right tool.

Mr. Alec I just want to say thank you for the knowledge! I have been rec diving for only 6 years. I average about 18 dives a year with 12 or so being in the same week in pretty blue water annually.

Hi Alec This Video helps a lot. I just changed settings for holidays (sea water, one 1.Stage). Normally I dive with two 1. Stages in Freshwaterlakes of Europe (because of the risk of iced 1. Stages). The Setting is not easy and i did it wrong the first time (the hose to the drysuit and the hose to BCD from the same 1.Stage...). This would lead to loss of buoyancy control, if one 1.Stage has to be turned temporarily off in case of an iced system. And then there is the problem of space and best hose setup... A tectipp would probably safe a lot of time screwing and checking. I'll keep on watching and learning. Thanks a lot for checking Yours Peter

@AlecPeirceScuba_SeaHunter

7 жыл бұрын

Some divers use a separate pony bottle for their drysuit for the same reasons - it lowers the risk of a freeze-up and doesn't use the diver's breathing air. For those not aware of this issue, the Adiabatic internal temperature drop in a scuba reg is related to the volume of air passing through it (among other things). If you are breathing through your primary regulator, your buddy is using your safe second, you are adding air to your BCD and to your dry suit, there's a lot of air passing through the first stage and that will cause a significant drop in temperature. If it's already in cold water, it is much more likely to ''freeze-up'. I put freeze-up in single quotation marks to indicate that it is not a totally correct term. The regulator doesn't really freeze. The moisture in the air freezes (yes, there is moisture in air - even scuba air) and the resulting ice causes a free-low that exacerbates the process into a full blown freeze-up. However, that's a topic for another vid. Thanks for your comment. Alec

I really wanna get rid of the rubber hose on my Octopus, it is heavy and not flexible at all. Those flex hoses are the best choice. And plus, because of the low-pressure port on my "Kraken" is so close to the intake hose, I can't even put the hose protector on because there is no room to put on a hose protector between the intake hose and the low-pressure port. I might have to change it to flex hose for my safe second.

@AlecPeirceScuba_SeaHunter

Not really. A very slight smear of silicon grease can't hurt but you run the risk of putting grease on the O-Ring which is not good. Assuming the O-Ring is new and in good shape (which it should be if you're changing hoses), it should not be greased or it can extrude and leak. So if you feel compelled to grease the threads, put the tiniest smear on the very end of the threads so the grease won't reach the O-Ring. Note that the hoses are only put in with low torque so the likelihood of them seizing is almost nil. They don't need grease to protect them nor to facilitate their insertion or removal. Thanks for watching. Alec

Hi Alec. I really enjoy you videos and thank you for sharing your knowledge. I just replaced a hose on primary. I followed your instructions using two wrenches etc. After I was done the reg would free flow as soon as the air was turned on, not even submerged. It had to be adjusted to correct it. Whilst replacing the hose I noticed the fitting may have moved ever so slightly and I tried to ensured it was exactly as it was when attaching the new hose. If that fitting moves slightly (if it did it is no more than 1/8 of a turn) can that cause the free flow. Thanks for any advice you may offer.

If your reg hoses are the usual rubber style, hose protectors are a good idea. I always put them on new regs for my customers. If the customer didn't want to pay the $10 for them (4 @ $2.50), I put them on anyway at no charge. It simply saved the aggravation later when he came back with a torn or frayed hose at the metal ferrule by the first stage. If you are VERY careful when packing and using your reg to ensure the hoses are never bent too sharply, you might be OK but I've seen helpful boat divemasters bend them or even drop them. I think they're a good idea. Don't forget to rinse underneath them occasionally. Alec

Alec, First, congratulations on your retirement. I have a question about when to get my regulator set serviced. I have watched all of your videos on maintenance and cleaning the first stage and octo and I follow them religiously after every dive. I am trying to understand if this maintenance precludes the need to get the regulator overhauled every year by a certified technician, or if the yearly service done by a dive shop is necessary or even just prudent. Thanks, Josh

@AlecPeirceScuba_SeaHunter

7 жыл бұрын

Your question is loaded with 'ifs' Joshua and I'll likely draw some fire but, here goes ... The short answer is that the only reason to take your regulator for an annual service is to keep the warranty in place. If that's not a concern and if you don't dive a lot and if you carefully rinse the reg after every use you probably can easily get by with a check every 2 or even 3 years. And find a dive store that will do a Check-Up, not a full service. If it's in good shape and working well, you don't need to spend $150+ for a full service. That would be like replacing your car tires because they're dirty! Note that all manufacturers used to require a 1 year service period. That has changed now for most big brands to a 2 year service interval. This was done without any change to the regulator so obviously they feel that every 2 years is OK. Also note that a regulator just sitting around can deteriorate - seats take a set, diaphragms and exhaust valves dry out and so on. If it hasn't been used for along time, say 1 year or more, get it checked out. Hope this helps. Alec

I sold my last scuba shop and retired from the business a few years ago. These videos are how I share my experience with divers everywhere. As for tape, modern regs do not need any tape, anywhere. The o-ring is what seals hoses tight, not metal-on-metal. Yes, there are specific o-rings for each hose and connection. O-rings specifications are standardized so don't use home or auto o-rings for scuba. Look at my videos on 0-rings for detailed explanations about this. As for cheap o-rings, is your life worth 10 cents more for a name brand vs unknown ring? Glad to help show that strength is NOT needed when tightening hoses. Thanks for watching. A

Mr. Alec, would it be better or worse to remove the hoses from the first stage if the gear will be stored for 3 months or longer? Just put the port plugs in place, the hoses can be coiled better and the first stage can be placed inside a thick pouch to provide better protection during storage or travel. Assemble again only when preparing for a dive trip and keeping on hand spare o-rings and tools.

Gosh that's a lot of work. It wouldn't be bad but I don't think it's necessary. If the reg is rinsed of all salt and dried well, just coil it lightly and seal it in a ZipLoc bag.

I linked this video for someone to watch, and ended up watching it myself again. One thing I wanted to add is that I am increasingly seeing more metric hose ends. I changed a SPG hose the other day, and my usual SAE wrenches didn't fit perfectly on the new hose, but when I used metric wrenches they did. I think this is probably fallout from the US based hose manufacturer, Danicorp, closing.

Hi Mr Peirce thanks for yet another great video, what's your thoughts on that i/we should perhaps apply a little O'ring grease or vaseline on the fittings before sliding the hose protectors into place? Would that help protect the fitting ect a little more or cause more problems in between cleaning intervals?? Regards Stuart

@AlecPeirceScuba_SeaHunter

7 жыл бұрын

Be careful with Vaseline. Some brands have petroleum-based products in them. Use real O-ring grease. It doesn't have to be food grade. Putting some grease on the tubing and outside of the fitting will allow you to put the hose protector on and off more easily and it might slow corrosion of the fitting. Don't make the mistake of lubing the O-ring as most divers do. A new O-ring should NOT be greased. That just facilitates extrusion of the ring. Many new O-rings, such as for cameras, are not supposed to be greased at all! If you feel compelled to grease the hose ends when installing them, you are probably suffering from silicon addiction. Just the smallest amount, just a light smear, not even a dab, on the threads is OK. If you can see the grease on your fingers before you smear the threads, it's too much. Look at the O-ring in the light. If the O-ring is shiny, glossy, it's good. Do not grease it. Take care. Alec

Assuming the O-ring on the regulator end of your new hose is fresh, it should NOT be lubricated. Particularly on HP fittings, lubrication may lead to extrusion of the O-ring. You can check the O-ring by simply looking at it under a good light. It should look glossy, not flat or dull. The HP hose fitting has a static O-ring so it does not move once installed. It does not need lube. Alec

Hi Alec, just a quick question, I saw your video on the flex hoses so I decided to replace my two regulator low pressure hoses. I ordered the yellow octopus and I ordered a red for my second stage, but when I went to change out the second stage, the connection on the new hose was smaller than on the first stage port, so I was wondering why that is, if you have any idea. I thought I ordered the right hose the description called it a second stage flex hose. Thanks

Hmmm. The only possibility that I can think of is that your regulator "features" 1/2" LP ports. A very few manufacturers made the LP ports larger on the premise that it would give the diver more air. Of course, the hope was that divers would buy their regulators. Pretty silly actually since the standard 3/8" ports will supply enough air for 5 divers at the same time! Plus, having a larger port but then forcing that air flow into the same size small hose offers no advantage at all. If that's the case, you will need to exchange the hose for ones with a 1/2" male end or, buy an adapter that's available from any dive store. They may not have it in stock but they can order it for you from Trident Dive - Catalog #AA48. Let me know. Alec

You must have a Scubapro tool to change their hoses. I know, I know. A pair of pliers will work but what a mess!!! The threads are the same as all other hoses so you can put any hose onto a Scubapro reg that you want. But to remove or install a Scubapro hose, you need the tool to grab the splines on the outside. It has no hex as you say. You can get the tool in 2 ways. Scubapro has a reg Universal Tool with several parts for doing a bunch of different things - things you'll never do yourself. It costs $50-$60. Or you can get a splined tool just for the hose fitting. It's about $20-$25. scuba-clinic-tools.com/products/scubapro-splined-wrench If you buy a tool, be sure it's metal. The plastic ones will break pretty easily. The best source for regulator tools is Scubatools.com . Nice people, good prices, high quality and they have everything. And don't go crazy when you tighten them. They are O-ring sealed. Just firm pressure. It's not an engine head bolt!! Hope this helps Alec

Alec, any easy way to install a hose protector? Seems awfully difficult

@AlecPeirceScuba_SeaHunter

Hose protectors can be a real pain to install. There are several ways to make it easier. 1. Take it to your LDS. 2. Soak it in hot, soapy water and spray some silicon grease on the hose. That MIGHT help. 3. Buy or make an installation tool. It's a simple rod, 8" long and about 1/2" in diameter with a female (inside) thread on one end that goes onto the hose fitting. Thread it onto the end of the hose. Put the how, soapy protector over it and you can pull the protector onto the hose. You can see one in the Trident catalog on page 34, #SA05. 4. Dive stores use a sophisticated version of that same tool which allows them to install both LP and HP hoses at the same time with little or no effort. It's o the same page in the catalog. They still use hot, soapy water or maybe some silicon grease. Good luck. Alec

Alec, what are your thoughts on using hose protectors with flex hoses? I'm thinking of removing them from my gear, and have received conflicting opinions on whether or not that's a good idea. Thanx!

Funny you ask. I don't recommend hose protectors with flex hoses. Some dealers will freak at this but surely their business doesn't depend on sales of hose protectors! Flex hoses are so flexible that they are less likely to bend and tear at the metal end. Since one of their biggest benefits is their light weight it doesn't make sense to put a rubber hose protector on it., I've been using them that way for over 4 years with many dives and no hint of a problem.

Do you use 75 or 90 duro o-rings on the LP port side hose?

@AlecPeirceScuba_SeaHunter

5 жыл бұрын

The LP O-rings are NOT subject to wear from dynamic forces or heat or high pressure so they are usually 75 Duro. Even other static O-rings in a scuba regulator are usually 75 Duro. There is no heat, no oxidation, no destructive fluids. Generally you are always best to use original factory-supplied O-rings. They are chosen to do the best job. Here is a link to the best O-Ring manual I've ever seen. If you need to know anything about O-rings, go here: www.physics.harvard.edu/uploads/files/machineshop/epm_oring_handbook.pdf Thanks. Alec

You did not use any lubricant on the threads or o-orings on the hoses. My local shop lubricates three threads and o-rings. Which is correct?

@AlecPeirceScuba_SeaHunter

4 жыл бұрын

Fresh O-Rings in a static position do NOT require lubrication. In fact, lubrication may be detrimental and lead to extrusion and loss of the O-Ring and subsequent harm to the diver. Hose end O-Rings are static. O-Rings in a dynamic position should be lubricated. Swivels, pistons, etc, are dynamic. Now this assumes fresh, new O-Rings and likely synthetic material as most of them are now. Alec

Hi Alec, I recently got a new digital SPG that measures pressure, depth, and temperature. It came with a rubber hose already installed on it from the manufacturer, and I want to replace the rubber hose with a flex hose. However the manufacturer doesn’t recommend using a different hose, because it could void the warranty. What should I do?

@AlecPeirceScuba_SeaHunter

Жыл бұрын

Sounds like a great SPG but as for hoses, flex or rubber, the maker should not care unless they specify the exact hose to use. Works like recommend and could are not the same as 'must use'. Suggest email or use their website contact form to clarify if flex hoses are OK or why not. Flex are the standard for all new regs from low to high end so why the issue? Only think I can think of is if an air spool is required to slow the air flow into the SPG to prevent a pressure overload. Check your owners manual but ask anyway. Otherwise a warranty is a good think to have (especially if expensive) but get the makers input first. Never know if there is a really good reason or just old manual that was not updated. A

My 2nd stage is s600 on a swivel. How do I remove the hose please ?

@AlecPeirceScuba_SeaHunter

You'll need a Scubapro tool to grasp the knurled or ridged nut which is tight against the 2nd stage and a flat wrench to hold the swivel nut. Separate those 2 and you're all set. The swivel comes off the end of the hose easily. You can use slip pliers for the Scubapro knurled nut but you may mark the nut. Alec

How do you remove a stuck high pressure hose from the first stage? I don't want to force it cause it might break.

@AlecPeirceScuba_SeaHunter

5 жыл бұрын

If it's simply in very tight, there is little or no option other than to hold the reg firmly (maybe in a padded vise) and using a good solid proper fitting wrench, force it out. If it does not come out with reasonable force, hold the wrench firmly and strike the end smartly with a solid, non-metal object. Use a piece of 2x4 or a rubber mallet. At this point it will either release and come out easily or it will break the end fitting off. If it breaks then you will have to remove the piece inside the port which is fairly easy to do with an EZ Out or some other type of broken stud remover. I think the type that looks like a screw is better for this job than the ones you must drill a hole first. There already is a hole so the left-hand screw type of stud remover should work well. I hate to drill since you run the risk of touching th threads in the body. Since you're working with brass, it's all pretty soft so ought to be a straightforward job. Just take your time and work slowly. There is no magic trick to removing a stuck hose. Good luck. Let me know how you do. Alec

Thank you for the prompt reply. Can I spray WD40 and leave it overnight would that help?

@AlecPeirceScuba_SeaHunter

It can't hurt although I doubt it will make much difference. What's happened is that the metal hose end fitting has been forced tightly against the regulator body. This hose seals with an O-Ring as you know and the threads actually need to be only hand tight. It will not leak under pressure. However, they should be tightened a bit more than that to ensure they don't work loose. A BIT TIGHTER! Too many divers think they're installing wheels on a pickup and tighten them way too much. Good luck. Alec

I tecently got a scuba regulator for free I went ant got it serviced right away The hoses are in good shape But 20 years old Should i get new ones?

@AlecPeirceScuba_SeaHunter

If they were checked and show no signs of deterioration, no cracking, no problems at the ends, etc, I'd stick with them. A regulator stored badly may have ruined hoses after just a year or two. Stored carefully, rinsed, dry, in a cool place and sealed in a plastic bag, the hoses will last indefinitely. Trust your dive store on this. They would likely love to sell you new hoses if you needed them. Take care. Alec

Where can I buy a bench valve?

@AlecPeirceScuba_SeaHunter

5 жыл бұрын

You can check with Scuba Tools. There are a couple of companies that sell them. They are not cheap but it's not hard to make one yourself. Any good tank valve will do. The 3/4" thread on a tank valve is standard so you can make an adapter to connect it to a hose to run to your own scuba tank as a source of air pressure. Get the parts at any good hardware or gas fitting store. If you have a machinist friend, have him take a 3" square piece of steel and machine a 3/4" thread on one side for the valve and a through hole on the other side for a hose. Just grasp the block of steel in a vise, valve up and hose running to your tank. Alec

what about adding heat shrink tubing to the ends of the hose protector? then you can protect the hose protector, while keeping your hose protected...lol

Interesting idea. I'm more concerned about the hose fitting than the hose protector. If the fitting corrodes you'll have to replace the entire hose - $50+. I use shrink tubing all the time but I don't think it will keep water out. The water will get trapped in there and ruin the fitting. Keep thinking though. Alec

When I have my regulators serviced the shop lubricates the o-rings and the threads with christolube. You did not do that.

@AlecPeirceScuba_SeaHunter

Christo Lube, or any other oxygen-compatible grease, is essential IF the regulator is to be used in EAN (enriched air - higher oxygen content than atmospheric.). Otherwise it is not. Most manufacturers are now recommending the use of O2-compatible grease at all times but that is based on their aversion to liability. That's not bad nor stupid. It's just unnecessary. Many dive stores also insist on the use of O2-compatible grease, partly for the same reason and partly because they make more money by doing so. There is no reason to NOT use O2-compatible grease any more than there is no reason to use racing oil in your Toyota. It will work just fine. Alec
